Yep I want to be sure no one is still having the problem and not rush into it so we'll see if anyone's reported a problem by the end of the week first. It can take a long time to track down a problem as you've noticed so I don't want us rushing into a change before we are very confident it's actually the soloution. But it does seem to be the www. that was the issue
